Website posts facing trouble in getting open in the original state

Post Cloudflare integration on my website its speed has drastically reduced and all posts of my website not getting open in their original state.

E.g. https://rockgrow.com/help-support/

error 3 error

https://rockgrow.com/jobs-careers/employee-referrals/

Though pages are working fine.

I can confirm the layout problems, however, your domain and website are not using Cloudflare.

Yea, I deleted my account with Cloudflare afterward but that too didn’t resolve the issue
